Mirror of the Abyss (quest)

Summary
The only known way for living people to get to the Abyss is through a portal called The Mirror of the Abyss. It is a black but reflective circle. However, the mirror was broken into shards which were scattered around the continent. It was the Marvelous Misadventurers' job to reconstruct it..

Shard 1
Beatrice had it.

Shard 2
The party traveled far south into the great desert. On the way, they stopped by a lone building and got some desert clothes from the dude there. He also turned their horses into camels. They arrived in a small desert village, and learned that the ruins near it had recently become dangerous. Also their camelhorses learned how to hoofpaint. In the ruins, they fought some bandits and got past some traps. Then, they had their second encounter with Bramwell Mad-Dog. They defeated him (he survived again) and continued. In the final chamber, one of the bandits touched the mirror shard and got violently transformed into a disgusting tentacle demon monster. They killed that and recovered the shard with an anti-magic bag.

Shard 3
The party learned about a shortage of mithril, and went to the customs office to investigate. There, they found out that no shipments have been arriving from Flo Rida. The party journeyed there and learned that their mithril mine had recently been populated by monsters. They went in and killed some stuff and recovered the shard.

Shard 4
Weird stuff had been happening in Spruce River, a city in Aronia. The party, of course, went there to investigate. Upon arrival, they found a giant spider in the rich neighborhoods, but the guards defeated it. They learned of a rich man named Enrique who recently acquired something weird from an auction. Instead of asking him about it, Karen and Sawysee broke into his house. They stole some clothes, jewelry, and the shard.

Shard 5
The second to last shard was in the Fey Wild. They took the route there through the enchanted forest. In the Fey Wild, they found it was darker and more menacing than it should be. They also met Conrad. Some fairies blew him up. They found the shard being guarded by the Chain Devil, the Demon King's right hand man. They put him in a bag of holding, but he tore his way out and returned to the Abyss.

Shard 6
The final missing shard was in Tredoit, a low-income town in the south of Aronia. They arrived and learned that the town was mainly under the control of two rival gangs, the Poisoids and the Frostfangs. Since they knew Madam Poisoid, they killed all the Frostfangs in a warehouse, and then killed their leader which was a vampire. During this time, they played basketball with the urban youth. They also got the shard.

Side quests
After completing the mirror, but before activating it, the party completed the Battle Fight and Pyramid side quests.

Finale
The Demon King, knowing that TBD was betraying him, took away his power. Sawysee went off to pick flowers.

In order to activate the Mirror of the Abyss, it needed a sacrifice. Beatrice brought in a prisoner to be sacrificed. Euro killed him, and the portal opened. They went in with Beatrice, paid the toll over the River Styx, and jumped down the chasm of memories to floor 666.

While falling down the hole of memories:

Saibo remembered his lowest point, and finding Helm.

Karen remembered taking some kids from an abusive owner.

Euro remembered fighting against Iblis in a desperate attempt to save his village.

Dragnorf remembered abandoning his crew.

Beatrice remembered some stuff too.

They finally made it to the bottom, and fought the Chain Devil and then the Demon King. There was also a dancing fire elemental making the room hotter.

The party weakened him, and then Beatrice used her magic (and 2 bottles of magic G-fuel) to seal him into an amulet. She then gave the amulet to TBD, who can draw on its power to summon his magic.
